Abstract

Image transfer in linear and curvilinear arrays of glass spheres was studied experimentally and discussed analytically. Glass spheres of 5 and 1 mmØ were used. The image pattern was successfully transferred through the sphere array but was highly deformed because of aberrations of the spheres’ lenses. However, we suppressed the aberrations significantly by filling the spaces between the spheres with dielectric liquid and covering both ends of the tube that contained the sphere arrays with flat plates.
